Your Price Guide: How Much Do Solar Panels Cost in 2025?
Discover how much solar panels cost in 2025, average solar panel prices, factors affecting solar panels for the home, and affordable solar power options.
Note: Costs are expressed in constant 2024 US$ per watt. Global estimates are used before 2010; European market benchmarks thereafter due to limited data availability. Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system components.
The size of your solar power system, measured in kilowatts (kW), is the most important factor affecting solar panel prices. Naturally, larger systems cost more than smaller ones, but they usually offer a lower cost per watt. Solar panels typically account for 12 - 18% of the total installation cost.
They store the energy accumulated from the solar panels. The price varies based on the installer, application and location. Batteries typically cost $12,000 to $22,000, according to the Department of Energy, although smaller capacity systems are available for less. In some cases, solar batteries may be more expensive than solar panels.
Larger systems, which produce more electricity, will naturally cost more. However, the cost per watt often decreases with larger systems due to economies of scale. For example, while a small 4 kW system might cost around $3 per watt, a larger 10 kW system might only cost $2.50 per watt. Not all solar panels are created equal.
